There's a theory that every particle is cabable of storing information, a bit like a hard disk, and sometimes stored information gets played back as a sound or a hologram. That also accounts for people who think they've existed in a previous life - memories have been passed through living cells...
I used to think that, but after reading about some of the modern scientific theories on consciousness and holographic theory I'm not so sure.
To me the idea of a creator is a bit absurd, and the idea of heaven and hell even more so, but if you ask if there's such a thing a a soul and can it...
